Working Principles

The 74ALVC162374TX operates based on transparent latching principles. When the latch enable signal (CLK) is active, the input data (D0-D15) passes through to the corresponding output pins (Q0-Q15). The outputs can be put in a high-impedance state by activating the output enable signal (OE), allowing other devices to drive the bus. The master reset signal (MR) resets all outputs to a known state when activated.

Detailed Application Field Plans

The 74ALVC162374TX finds applications in various electronic systems that require efficient data storage and transfer. Some potential application fields include:

1. Microcontrollers: Used for interfacing microcontrollers with external memory or peripheral devices.
2. Communication Systems: Facilitates data buffering and routing in communication systems such as routers and switches.
3. Industrial Automation: Enables efficient data transfer between sensors, actuators, and control units in industrial automation systems.
4. Automotive Electronics: Used in automotive electronics for data storage and transfer in control modules, infotainment systems, etc.
